For this purpose, the technology employed by the present utility model is a kind of centering body of Heavy-duty chassis dynamometer, including become
Frequency motor, feed screw nut's elevator, further include to middle cross beam, centering guide rail bracket, centering support plate, it is described to middle cross beam left end
Front and rear sides, right end front and rear sides be each provided with the centering guide rail bracket, shape between the centering guide rail bracket of left and right ends
At space for arranging rotary drum, to being each provided with the variable-frequency motor, variable-frequency motor immediately below the left and right end of middle cross beam
Former and later two output ends pass sequentially through transmission shaft, commutation driver, feed screw nut's elevator respectively and drive centering support plate along right
Inclined guide rails synchronization lifting on middle guide rail bracket, when centering support plate is synchronous to rise, the centering support plate of the left and right sides is mutual
It draws close, when centering support plate is synchronous to be declined, the centering support plate of the left and right sides is separated from each other, centering support plate inner end
Centering roller is provided with for pushing tow wheel.
The inclined guide rails being arranged on the centering guide rail bracket as a preferred embodiment of the above solution, totally two, and be parallel to each other and set
It sets, is fixedly installed with below the centering support plate and is oriented to slide post correspondingly with inclined guide rails.Simplify structure, and really
The inclined guide rails that centering support plate is arranged along centering guide rail bracket are protected steadily to go up and down.
The utility model has the beneficial effects that variable-frequency motor is driven by transmission shaft, commutation driver, feed screw nut's elevator
Inclined guide rails of the centering support plate on centering guide rail bracket move, and can be adjusted to driving wheel of vehicle tire and rotary drum center weight
It closes, centering has enough thrust.For uniaxial vehicle centering, centering support plate can be moved up；It, can for for-wheel vehicle centering
Centering support plate is moved down, for-wheel vehicle is allowed to straddle on rotary drum.Major advantage using the above structure is:
(1) inclined guide rails of the centering support plate on centering guide rail bracket move, and bearing capacity is strong；
(2) power transmission only passes through transmission shaft, commutation driver, feed screw nut's elevator, and drive mechanism is simple, transmission effect
Rate is high；
(3) centering support plate is mobile when centering, except uniaxial wheel is suitable for China and foreign countries, is also applied for pair of biaxial wheel
In.
